How to Choose Oleaster
When choosing oleaster, look at the skin color and firmness; fruits that have turned silvery brown and softened slightly are sweeter and mealier.
- Greenish, firm fruits are not yet ripe and are astringent.
- Fruits with wrinkled skin that are excessively dry may be stale.
- When fresh, the fruit should feel slightly moist; when dried, it should be firm and durable.
How to Store Oleaster
Fresh oleaster lasts for a few days at room temperature; refrigeration extends this period somewhat. For long-term storage, dry it in the sun; dried oleaster keeps for months without spoiling and can be ground into powder for use.
